AFFINITIES. 



1. With E. Behriana, F.v.M. 



As shoAving how difficult it sometimes is to deal Avith closely related forms, I 

 have two specimens, apparently identical, sent by W. K. Bissill, of near Bendigo, 

 Victoria, to the Melbourne Herbarium at different times. Mueller labelled one 

 " B. heniiphloia, a form verging to Behriana,'" and the other " E. Behriana, transit 

 to B. hemiphluia.'''' I have also specimens, apparently identical, from the Mallee 

 country of Mctoria, labelled variously by Mueller B. hemiphloia, E. Behriana, and 

 B. laryijlurens [bicolor). All these are Mueller's own species, and I can give no 

 better illustration of the way in which it is sometimes difficult to discriminate 

 between species from herbarium material alone. (See Part X p. 337, vol. 1 of this 

 work.) 



2. With E. bicolor. See p. 12. 



3. With E. popiilifolia, Hook. 



E. j'OjnilifoUa has usually egg-shaped or " poplar " leaves, which, as a rule, 

 are different enough from those of var. microcarpa as it is commonly observed in 

 westei'n New South Wales, but lanceolate leaves are marked in specimens of 

 B. populifolia, from various localities. It is, in fact, strange as it may at first 

 appear, not always easy to separate var. microcarpa from E. populi/olia, not only
